Transcript

  • 1. TISSUES
    • Tissues are groups of cells similar in structure and function
    Epithelial Connective Muscle Nerve Erin Ruthe G4
  • 2. EPITHELIAL TISSUES
    • Epithelial tissues are classified as either simple or stratified
    • The shape of epithelial cells are squamous, cuboidal, and columnar
    Simple Squamous Simple Cuboidal Simple Columnar Stratified Squamous Stratified Cuboidal Stratified Columnar Pseudostratified Columnar Transitional
  • 3. SIMPLE SQUAMOUS EPITHELIA
    • Composed of a single layer of flattened cells
    • Used for diffusion and filtration
    Simple Cuboidal Simple Columnar Stratified Squamous Stratified Cuboidal Stratified Columnar Pseudostratified Columnar Transitional Epithelial
  • 4. SIMPLE CUBOIDAL EPITHELIA
    • Made up of a single layer of cube-like cells with a large, spherical central nuclei
